STI Surveillance: Annual Report 2001

Saturday 29th January 2022


Chlamydia infections (the commonest bacterial STI in New Zealand) are still increasing and may soon overtake genital warts as the most common infection in sexual health clinic patients.

Notifications of C trachomatis by participating laboratories increased during 2001 to 8668 cases representing a rate of 502.7 per 100 000 population which is five times higher than that reported in Australia during the same period. Similarly, rates of N gonorrhoeae, at 53.2 per 100 000 population almost doubles that of Australia.

Groups at higher risk, by STI, are:
Maori and Pacific peoples
Young people aged <25

Maori and Pacific peoples
Males aged <20

Genital herpes:
Maori and Europeans
All age-groups

Genital warts:
All ethnic groups
Young people aged <25

Cautionary note:
This report summarises the epidemiology of STIs, using data from SHCs, FPCs, SYHCs and diagnostic laboratories in New Zealand. The figures presented here may underestimate true infection rates because not all clinics and laboratories participate and STIs diagnosed by a range of other health care providers, such as GPs, are not included in this report. It is also important to note the denominator used in calculating disease rates. Rates based on clinic data use the total number of clinic visits, whether for STIs or other conditions, as the denominator. Rates based on laboratory data use the total ‘usually resident’ population, in the District Health Boards covered by laboratory surveillance, from the 2001 New Zealand Census.
